Quantum Edge Detection
Santiago Llorens, Walther González, Gael Sentís +3
This paper introduces quantum edge detection, aimed at locating boundaries of quantum domains where all particles share the same pure state. Focusing on the 1D scenario of a string…
Phase estimation with limited coherence
D. Munoz-Lahoz, J. Calsamiglia, J. A. Bergou +1
We investigate the ultimate precision limits for quantum phase estimation in terms of the coherence, , of the probe. For pure states, we give the minimum estimation variance att…
Wave-particle duality relations based on entropic bounds for which-way information
Emilio Bagan, Janos A. Bergou, Mark Hillery
We present wave-particle duality relations involving the relative entropy coherence measure, which plays a prominent role in the resource theory of coherence. The main input in the…
Unsupervised classification of quantum data
Gael Sentís, Alex Monràs, Ramon Muñoz-Tapia +2
We introduce the problem of unsupervised classification of quantum data, namely, of systems whose quantum states are unknown. We derive the optimal single-shot protocol for the bin…
A generalized wave-particle duality relation for finite groups
Emilio Bagan, John Calsamiglia, Janos A. Bergou +1
Wave-particle duality relations express the fact that knowledge about the path a particle took suppresses information about its wave-like properties, in particular, its ability to…
Duality games and operational duality relations
Emilio Bagan, John Calsamiglia, Janos A. Bergou +1
We give operational meaning to wave-particle duality in terms of discrimination games. Duality arises as a constraint on the probability of winning these games. The games are playe…
